Abstract
A directed energy deposition (DED) additive manufacturing system for manufacturing a component from a material includes a deposition assembly having a deposition head through which material is deposited to form a top surface of a component. The top surface defines a width (w) measured in millimeters (mm). The deposition assembly also includes compression rig having a compression head. The compression head is configured to apply a compressive force (F) measured in kilonewtons (kN) to the top surface of the component. The compression rig also defines a target load (Y).

A directed energy deposition (DED) additive manufacturing system for manufacturing a component from a material, comprising:
- a deposition assembly having a deposition head through which material is deposited to form a top layer forming a top surface of a component, the top layer defining a width (w) measured in millimeters (mm);
- and
- a compression rig comprising a compression head, the compression head configured to apply a compressive force (F) measured in kilonewtons (kN) to the top surface, and wherein the compression rig defines a target load (Y) per unit length equal to:
- F
- w
- ;
- wherein the target load (Y) is greater than or equal to 4 kN/mm and less than or equal to 19 kN/mm.
A method of manufacturing a component, the method comprising:
- depositing a stream of material via a deposition head onto a build surface, the stream of material defining a width (w) measured in millimeters (mm);
- and
- applying a target load (Y) to a top surface of the component via a compression head, the target load (Y) based on a compressive force (F) exerted onto the top surface of the component by the compression head and the width (w);
- wherein the target load (Y) is equal to:
- F
- w
- ;
- and
- wherein the target load (Y) is greater than or equal to 4 kN/mm and less than or equal to 19 kN/mm.
